ALVIN T. SIMPKINS, yOF ST. LOUIS, MISSOURI.

BAKE/RS OVEN.

SPECIFICATION forming part of Letters Patent No. 355,568, dated January 4, 1857.`

Application filed July 20, 1886.

serial No. 208,525. (No moan.)

.To all whom t may concern.:

Be it known that I, ALviN T. SIMPKINs, a citizen of the United States, 'residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement inBakersVOvens, of which the following is a full, clear, and exact description.

My invention relates to improvements in the construction and arrangement of bakers ovens, and has for its object to prevent the overheating ofthe rear end of an oven and consequent burning of the bread placed thereat before the bread placed at the front part of the oven is sufliciently baked, which is more or less the case with the bakers ovens in present use.

In the accompanying drawings, Figure l-is a side sectional view of my improved bakers oven; Fig. 2, a sectional plan on line 1 1 in Fig. l; Fig. 3, a transverse section on line 2 2 in Fig. l, and Fig. 4 a sectional plan on line 3 3 in Fig. l, like letters of reference denoting like parts in all the figures. h

In carrying out my invention I dispense with or stop off the vertical flue usually provided behind the rear end of the oven, and prolong the oven-chamber a back to the rear wall, b,of the brick setting. Beneath theoven a, at a suitable distance forward from the rear wall, b, is an upright wall, c, which sets against the under side of the oven a and extends transversely for the entire width of the latter 'between the side walls` d, thereby stopping off the passage of any direct heat behind the rear end of the oven a, the space between the walls o and b being filled with dirt, rubbish,or other suitable material,e. Between the Wall c and the bridge f of the re-place y are arranged above the crown of the oven a, and thence return through similar lues, l, to the exit-liuc m, in front of the' oven'. Byvthis means the heat is uniformly distributed over the bottom and top of thev oven a without the action of any direct heat at and behind the rear end of the latter, as at present the case, so that a more uniform temperature is imparted to the interior of the oven,and the loaves of bread placed therein are properly and equally baked Without the necessity and trouble of shifting the loaves.

I claiml. In bakers ovens, the upright wall c, in combination with oven a and side walls, d, of brick setting, substantially as shown, and for the purpose described.

. 2. In bakers ovens, the upright wallc, horizontal flues ij, vertical iues'k, and horizontal fines Z Z', in combination with oven a, substantially asshown, and for thepurpose described.

In testimony whereof I affix my signature in presence of two witnesses this 17th day of July, 1886.

ALVIN T. SIMPKINS.
